Drug tunnel discovered beneath U.S-Mexico border

NOGALES, Ariz. 
Another tunnel apparently dug by drug smugglers has been found beneath the U.S.-Mexico border in Nogales, Ariz.

The U.S. Border Patrol said the 83-foot-long tunnel, which was constructed with side walls framed with wooden studs, was found Wednesday. Agency spokesman Michael Scioli says it was large enough for a person to crawl through on their hands and knees.

The discovery followed the arrests of two people last week who were caught digging a hole in the floor of a Nogales building. Agents went to the building after someone reported hearing construction activity inside.

Scioli said it's the 63rd smuggling tunnel found beneath the border in the Nogales area since October 1995, and the 16th since last October.
